Abstract
We report an experimental and theoretical study of whispering-gallery-mode propagation of subpicosecond terahertz pulses in a dielectric cylinder coupled by means of a dielectric slab waveguide. We observed repetitive cavity pulses from this structure for which the output pulse shapes were determined by the multi-whispering-gallery-mode coupling into the cylinder. A coupled-mode theory derived for this cylindrical system and coupling structure gives reasonably good agreement with the experiment in both the frequency and time domains.
